This is never good style, at least in the case of exec. exec is evil.
What works (beware that the below code is nevertheless untested and might
contain little warts) and is the "usual" and clean way to go:
### libinfo/__init__.py
# Empty.
### libinfo/Module1.py
def libinfo():
return "I am module1."
CFLAGS = ["-DMODULE1"]
### libinfo/Module2.py
def libinfo():
return "I am module2."
CFLAGS = ["-DMODULE2"]
### Importer.py
modules = {}
CFLAGS = []
def load_modules(to_load=["module1","module2"]):
global modules, CFLAGS
for mod in to_load:
try:
modules[mod] = getattr(__import__("libinfo.%s" % mod),mod)
except ImportError:
print "Could not load %s." % mod
continue
print "Module: %s (%r)." % (mod,modules[mod])
print "Modules libinfo: %r." % modules[mod].libinfo()
CFLAGS += modules[mod].CFLAGS
print "Total CFLAGS: %s." % CFLAGS
if __name__ == "__main__":
load_modules()
print "Module container: %s." % modules
### End Importer.py
HTH!
